What is food intolerance, how is it diagnosed and what can be done about it?

Food intolerance is the name we give any adverse reaction to a food or food additive that is not caused by an allergy. It is the body’s metabolic reaction to various chemicals in food or drinks, to the extent that an adverse reaction occurs. While some of the symptoms of food allergy and intolerance may be similar, an allergy involves the immune system, while an intolerance does not.
